Patent number: 8348244Abstract: A carburetor valve and limiter cap assembly for limiting adjustment of fuel flow in a carburetor may include a needle valve and a limiter cap. The needle valve may have a tip, a threaded portion, a head having a flange with an outer diameter greater than the rest of the head, and one or more serrations formed on the head. The limiter cap may have a sidewall, a tab extending outwardly from the sidewall, a first cavity having an inner diameter sized for an interference fit with the flange, and at least one driving feature to engage at least one serration so that rotation of the limiter cap causes rotation of the needle valve. The interference fit between the flange and the limiter cap inhibits removal of the limiter cap from the needle valve to prevent undesired adjustment of the needle valves by an end user.Type: GrantFiled: July 24, 2010Date of Patent: January 8, 2013Assignee: Walbro Engine Management, L.L.C.Inventors: Tetsuji Kojima, Hidenori Sasaki, Masashi Sasaki, Hitoshi Terakado

Patent number: 8165505Abstract: A developer cartridge includes a developer storing portion that stores a developer and has a first opening for taking out the developer, and a shutter member slidably mounted to the developer storing portion so as to open and close the first opening. The shutter member has a resilient-member-fixing portion to which a resilient member is fixed for preventing leakage of the developer through between the shutter member and the developer storing portion. A deflectable part is provided on at least one of the resilient-member-fixing portion and a peripheral portion of the first opening of the developer storing portion.Type: GrantFiled: August 21, 2008Date of Patent: April 24, 2012Assignee: Oki Data CorporationInventor: Tetsuji Kojima

Patent number: 8138421Abstract: A flexible flat cable capable of having good flexibility and good bending strength while reducing a thickness thereof without damaging a good electrical characteristic of a strip structure and capable of enhancing cost effectiveness is provided. The flexible flat cable includes: an air-containing layer, serving as an insulating member, having a width substantially the same as a transmission path width of a cable body including a plurality of conductors arranged in a prescribed pitch, the air-containing layer being disposed in such a manner as to sandwich the cable body from both sides; and shield members disposed in such a manner as to cover a surface of the air-containing layer and to be conductively connected to a ground layer at terminal portions of both ends of the cable body. The air-containing layer includes non-woven fabrics cut in a width substantially the same as the transmission path width of the cable body.Type: GrantFiled: March 7, 2008Date of Patent: March 20, 2012Assignee: Sony Chemical & Information Device CorporationInventors: Hiroshi Takamatsu, Tetsuji Kojima

Publication number: 20090133898Abstract: It is to provide a flexible flat cable with a carrier tape capable of preventing conductors from being bent without increasing the cost of production. The flexible flat cable with the carrier includes a plurality of flexible flat cables 2 each of which has a plurality of conductors 2a sandwiched between two insulating materials 2b and arrayed substantially in parallel at a prescribed pitch, with the conductors 2a at opposite ends of each flexible flat cable exposed in a prescribed length, and a carrier tape 3 for supporting thereon surfaces of the flexible flat cables on one side thereof. The plural flexible flat cables are continuously arrayed and laminated with the carrier tape 3 in a state in which the conductors are individually cut off in half.Type: ApplicationFiled: June 1, 2007Publication date: May 28, 2009Inventors: Tetsuji Kojima, Hisaya Tamura

Patent number: 6896245Abstract: A stratified scavenging carburetor with a lost motion coupling permits limited relative movement of a throttle valve relative to an air valve so that initial opening of the throttle valve off idle does not open the air valve to avoid diluting with scavenging air the fuel and air mixture delivered to an engine. Rotation of the throttle valve beyond a predetermined amount from idle causes a corresponding opening of the air valve to provide scavenging air to the engine. Closing a choke valve engages a lock lever with the throttle valve to move the throttle valve off idle to a start position without opening the air valve. In another embodiment, closing the choke valve prevents the air valve from opening even if the throttle valve is moved beyond where the throttle valve would cause the air valve to open if the choke valve were open. Thus, a richer than normal fuel and air mixture can be supplied to the engine during a choke-assisted start and warm-up of the engine.Type: GrantFiled: November 21, 2003Date of Patent: May 24, 2005Assignee: Walbro Japan, Inc.Inventors: Masao Suzuki, Hiroshi Nagata, Tetsuji Kojima
